US helps Ukraine return 2 bombs' worth of uranium

WASHINGTON  — In a secret operation to secure nuclear material, the United States has helped Ukraine return to Russia enough uranium to build two atomic bombs.
This week's removal of more than 110 pounds (50 kilograms) of highly enriched uranium followed a pledge by Ukrainian President Viktor Yanukovych to get rid of all of his country's highly enriched uranium by April 2012. The material will be blended down in Russia, rendering it useless for bomb making.
Details of the operation were provided to The Associated Press by the National Nuclear Safety Administration.
